Free-shaped floor surface vehicle

ABSTRACT

[PROBLEMS] To more increase the capability of a vehicle despite the fact that mankind cannot catch up an increase in performance of the vehicle by forming the vehicle to give less damage to persons in the event of the accident of the vehicle and to minimize emission from the vehicle. [MEANS FOR SOLVING PROBLEMS] The safety of occupants in the vehicle depends upon the degree of collapse of the vehicle at the time of collision. The non-pollution of the vehicle depends upon the speed to the design change of the vehicle to alter the specifications based on the latest technologies. For this purpose, a carriage allowing the easy design change must be developed. A structure allowing the easy change of the carriage portion of the vehicle has been developed.

TECHNICAL FIELD

This invention drastically improves the structure of the frame that becomes the truck of the vehicle, and changes the vehicle etc. to a flexible structure drastically. It is a technology that achieves a safe, flexible working condition. Technology therefore that makes it correspond by changing the composition of the division type frame that can correspond to the variable structure and the size into the truck structure.

The cause of the traffic accident is mostly the lower performances of the straight advancement. As the cause, it is that vehicles cannot be controlled in the direction by the steering wheel with slipping, the stone, and the falling object etc. and vehicles run to the wrong direction. It is technologies that greatly reduce the danger.

It is a technology that the convenience of the operation of the crew's getting on and off, the piling up and unloading the freight, and the work structure in the upper part improves greatly by freely changing the floor position of the vehicle.

The shock reduction at the collision is desirable by the vehicle being broken as buffer to reduce the damage of the crew. However, the way of thinking from the viewpoint that breaking the vehicle is little because it cannot help but take strength of the truck important from the present viewpoint of the design. In this technology, the main portion is technology in the respect that can correspond flexibly since it connects with the joint that can adjust the angle.

Since the vehicle uses many small sum diameter tires, safety in operation is very steady. The technology which controls the maintenance and the rotation difference of the tire is necessary. A conventional steering wheel mechanism becomes unnecessary by this technology; it is a technology that contributes to reduction in costs and the weight reduction.

The most important problem is the comfortable residence in the vehicle in the case that the structure of the vehicle is made flexible. It is necessary to use flexible materials as interior decoration.

The comfortable flooring which keeps water, dust, wind and temperature is necessary; it corresponds to the change of the floor shape flexibly, and has elasticity as the mat. But the progression of the material is drastically, it is necessary to select the material to fit the structure of the vehicle. The important thing is to select the material which can correspond to the structure of the vehicle flexibly, especially absorb the shock in the case of the accident.

It is a technology that enables the setting of the vehicle center of gravity point in which a free floor configuration and stability exist at the body each position along with a free setting and that of the minimum ground clearance by matching the combination of frames to the change in the angle of the joint and adopting the tire of the small sum diameter.

BACKGROUND ART

There are a lot of examples of manufacturing by monocoque structure of the passenger car and the bus conventionally. The track and the special vehicle are installation on the frame work of the all-in-one design, and the driving gear was often installed at the same time. However, both monocoque construction and frame work lacked the consideration at the time of the crew and the load getting on and off, the wholesale of the freight, and the load volumes to the operator.

The vehicle including the passenger car has emphases in durability and the great physical strength. Moreover, there were some respects where it lacked consideration for the safety because of being partial to the design, and were a lot of problems as the overall vehicle.

The truck part of the basic structure as the vehicle required a lot of time to achieve the result and to anticipate a large sum of money and goods for the installation, the experiment of the driveline system and the press manufacturing because the design of the substructure that centered on the floor for the passenger car is integral construction. It is required strenuous efforts and time to obtain the goods experiment with good performance.

A large labor for the reduction of shock to the crew was turned on by the crash of the vehicle for securing safety. Since it is not originally a vehicle which was thought by a flexible structural concept of the vehicle, it is difficult to achieve the result of the reduction of body shock to the crew by the effective damage of the anticipated vehicle.

Conventionally, there are examples that the contrived engine, the tire and the driving system of large scale bus are designed not interfere with each other, and the lower-floored truck has 4 axles and uses middle sum diameter tires, and the truck whose carrier part is lower because the rear wheel uses small sum diameter tires. These frames are all-in-one structure, or monocoque structure.

DISCLOSURE OF THE INVENTION

Problems to be Solved by the Invention

A large labor and the capital were necessary for designing the truck part in the vehicle of a conventional frame type and the monocoque type and the design for body manufacturing division that put above the truck part had the large restriction since it was not flexible each other. For solving the problem, the advantage of a frame work vehicle is looked over again, and frames are divided a lot and connected by the joint. It enables to make the frame type vehicle which can change the angle between the frames and the form of the frames, which makes it possible to design the truck part and body part easily, to cope with the request by the society and change the vehicles quickly. It reduces the all-in-one part structure of the truck part and the part of the large-scale manufacturing such as press manufacturing, and reduces the cost.

Means for Solving Problems

It reviews the goodness of the frame type in the vehicle, makes it the basic of the truck design. The vehicle of the frame form was difficultly inferior an integral stamping of the frame from respect of the cost and weight to the monocoque type, and was difficult correspondence to weight distribution at the truck design, and had the fault that gave strength to the part without the necessity. Therefore, it combines a lot of small frames and connect by the joint to solve the problem. Moreover, it is possible to design freely, prepare the safety design by having the structure which can change the joint angle.

The structure is divided into a necessary part for the engine, the transmission gear supporting section, the driveline system, the axle supporting section, the rear end part, and the part of safety practice etc. and each part is produced according to strength that is necessary respectively, and connect it with the joint that can adjust the angle.

The joint assumes the division type, and uses the motor by the oil pressure or electricity. The angle of joint is controlled by the use of the gear mechanism or the power by the cylinder method or using the oil pressure and air pressure by an electronically controlled technology that the program control is done and control the angle of the joint using the gear structure or the cylinder and the solenoid, etc.

The many small sum diameter tires are used, which can lower the minimum ground clearance, and the idling of the wheel on turning sideways of the vehicle, slipping on the dirt ground or the snow road etc. are decreased sharply. Moreover, the body of the vehicle can be prevented from reaching on the ground by the angle change mechanism using the connection of frames to keep a safe space from the lowest part to the ground, which improving safety.

The tire with each foil is divided and connected with the axle. The connected method cancels the number of an inside and outside tires and uses the actuator oppositely. It uses the differential gear for which it applied by Japanese Patent Application No. 2001-159758 changes the way of the vehicle by changing the number of rotation of the right and left axle by the control device programmed of the each number of rotations.

In the case that the suspension system for which it applied by Japanese Patent Application No. 2001-376608 as a suspension system of each axle is used, it can closely achieve the control of the body further.

The equipment that measures the space to the ground by infrared rays and the millimeter electric waves is set up to each part of the body, it always measure partial each space between ground and vehicles. As a result, the body of the vehicle can be prevented from reaching on the ground.

A free metallic board like a drainboard with free stretch to all directions as the floor of the vehicle is used. It needs the enough stretch in order to correspond to the collision of the vehicles and the change of the form of the entire integrated frames. A thick carpet is used that there are a waterproof property, elastic property, and dust resistance on the floor material. The mat with thin rubber is used between the floor material and the carpet.

At the vehicle crash, the vehicle adjusts the angle for the joint of the frame by the digital signal according to the procedure which is calculated beforehand to expect it and it dents the body. The material and shape are set so that the floor material may follow at that time.

The change for the progress direction is operated by the digital signal, and makes it progress in the direction that the driver intended by controlling the actuator in the front, back, left and right by a steering wheel or a cylinder shape controller.

Effect of the Invention

This invention can achieve the improvement of the customer's satisfaction by the entire externals in which it can simply do an improvement of safety, a great reduction in the improvement of the flexibility of the design of the truck part in the vehicle and the cost, and changes for body manufacturing division.
